I just tried to make a post on Mastodon and tag a community in it so that my post would show up in that community -- something I've done many times before.

However, in this case, there is a Lemmy user with the same name as the community, and it defaulted to tagging that user. Is there a way to tag the community specifically?

I didn't even realize that a user could have the same name as a community. I thought every fediverse actor had to have a unique at-name-at-domain handle, and both users and communities were actors.

I agree. Users shouldn't be allowed to choose a name that already exists as a community. But it would be a shame if communities could not be created because a user with that name already exists.

I think this is yet-another reason to have a separation between users and communities at the instance/domain level.

Setting up a server should require one top-level domain and two subdomains:

  • https://myserver.com/ would be for webfinger and the actual backend.
  • https://groups.myserver.com/ would be the subdomain for the AS2.Group actors
  • https://people.myserver.com/ would be the subdomain for the AS2.Person actor
